Boundary f1-score
WebMar 1, 2024 · All the images with Boundary-F1 score below the 2σ (Boundary-F1 ≤ 0.84) were identified. Only four images (2.6% of total testing dataset) had the Boundary-F1 score below the 0.84, which was primarily caused by erroneous background removal (some branches from background trees were within the threshold distance of 1.3 m). WebFor example, a beta value of 2 is referred to as F2-measure or F2-score. A beta value of 1 is referred to as the F1-measure or the F1-score. Three common values for the beta parameter are as follows: F0.5-Measure (beta=0.5): More weight on precision, less weight on recall. F1-Measure (beta=1.0): Balance the weight on precision and recall.
